SAND-GUARD FOR CAR-AXLE BOXES.

SPECIFICATION forming part of Letters Patent No. 235,298, dated December '7, 1880.

Application filed October 6, 1880. (ModeL) To all whom it may concern Be it known that I, HENRY Born, of New York city, in the county and State of New York, have invented a'new and useful Improvement in Sand-Guards for Car J ournal-Boxes and Journals, of which the following is a specification.

Figure 1 is a sectional elevation of the improvement shown as applied to a journal-box and journal. Fig. 2 is a sectional elevation taken through the line as m, Fig. 1. Fig. 3 is a perspective view of a part of the improvement.

Similar letters of reference indicate corresponding parts.

The objectof this invention is to furnish sand-guards for car journal-boxes and journals, to prevent sand from entering the journal-boxes and cutting the journals and brasses or bearings.

A represents a journal-box of any ordinary construction. B represents the journal of a car-axle, which enters the journal-box A, and upon which the brasses or bearings rest in the ordinary manner.

(J is a circular band or flange upon the in ner end of the journal-box A, and which may be formed upon the said journal-box A, or may be secured to the said journal-box by bolts, screws, or rivets. The drawings represent the band as having lugs upon its inner edge to receive the rivets by which it is secured to the journal-box. The band C is open at the lower side, as shown in Figs. 2 and 3, to allow any sand that may get Within the band to The band C surrounds the opening drop out.

in the inner end of the journal-box A, and protects the said opening from the sand.

D is a leather Washer placed upon the journal B and resting against the outer side of the 4.0 inner end of the journal-box A. The leather washer D fits snugly upon the journal B, so as to be carried around with the journal in its revolution, and is made of such a size as to cover the opening in the journal-box when the 4 5 brasses are new and when they are worn. The leather washer D is held up against the journal-box A by a shoulder formed upon the journal B, and may be strengthened by a ringplate of metal attached to the outer part of its 50 outer side. The leather washer D prevents any sand that may get within the band 0 from entering the journal-box A and getting upon the journal.

With this construction the journal and 55 brasses will wear much longer than when the guard is not used, a much less quantity of oil will be required to keep the journal lubricated, and the heating of the bearings will be prevented.

I am aware that a leather ring and metal plate have been held upon a journal by two portions of the box, and that a dust-plate and packing-ring have been held by a take-up bolt and spring; but

What I claim as new is A band, (3, made fast to the inner end of journal-box and open at the lower side, as shown and described.
